Err. Sorry, but this doesn't make sense to me.

The user agent makes an HTTP request to the server. The server runs
some code in an ASP.NET environment and returns an HTTP response. This
is then validated, the response might be valid, or it might not be

Where does a "web config file" come into it?

How does the validator differ from Firefox, Internet Explorer or
another browser?

The W3C Markup Validator is probably a better bet, since it is (a)
cheaper and (b) a validator (which, despite its name, the CSE HTML
Validator, isn't).

Well yes. You validate HTML, not programe code that generates HTML.
